Keep your cast iron pans seasoned and ready to cook with this non-aerosol spray. Adjustable spray settings deliver 100% pure canola oil as a drip, stream or uniform spray. Seasoning regularly helps prevent corrosion and builds up in increasingly nonstick layers. To use, clean and dry cookware thoroughly, then apply just enough oil to lightly coat cooking surface. Rub into surface with a clean cloth or paper towel, then wipe away any excess oil.
